Japan's NTT Corp. announced on the 19th that it has developed 'batteries that return to the soil' using biomaterials and fertilizer ingredients. "The company believes that with the advent of the Internet of Things (IoT) era, a large number of batteries, such as small sensors, It will be difficult to recover and is expected to have related needs.

NTT developed the 'return to the soil battery', characterized by no recovery, the battery can return to the soil, will not pollute the natural environment. Ordinary batteries use zinc alloy, rare metals and some harmful substances, but the new battery is the use of biological materials Wait.

According to NTT, there was no negative impact on the growth of vegetables after the batteries were mixed in the soil, but the battery capacity is small and research will be pushed forward for practical applications.
